STENGIL-PLATE.

Folge Srlgchitle referat in in time intiem ntent mit 'linking pitt nf the sans.

Bc it known that I, GEORGE R. POWERS, of Kingston, in the county of Plymouth, and State of Massachusetts, have invented a new andimproved Stencil-Plate, of which the following is a full, clear, and exact-descrip- '.ion, reference being had to the accompanying drawings, makingY a part of this specification, in which Figure 1 represents avertica-l section, showing two positions of the'stencil-plate; and

Figure 2, a bottom View of the device. Y

My invention consists in a circular stencil-plate provided with any desired words, letters, or figures, and attached to a. handle, and combined with a sliding-shell in such a manner that the said stencil-plate may be pressed down upon the surface ot' the object to be marked, and when a letter, gure, or other mark is made, spring placed within the shell will cause the plate to rise so that it can be readily turned to present another letter or figure in successionto the one preceding by simplysturning the handle.

Referringto the drawings, A represents a circular stencil-plate, having a series of letters, ligures, or other. marks concentrically in the same, and screwed or otherwise secured to the cylindrical Ashell B, which shell is firmly attached to the handled). Within the shell B is a. sliding cylinder C, over the upper part of which is arranged a spring, s, which serves to keep the said cylinder pressed outwardly. The cylinder C is rformed with a shoulder at the lower Tend, which rests against a disk, d, screwed to the lower end of the handle, by which it is prevented from passing out from the shell B. In the bottom of the cylinder are placed points p, for holding the device in position when in use. To the side of= the cylinder C is attached a spring, E, securely fastened at its upper end, and terminatingin a right-angular projection at itslower end, the said projecting part playing freely in a recess in the cylinder and {itt-ing lengthwise in notches e formed in the inner surface of the shell B, the said notches serving to hold the stencil-plate in proper position and preventing its turning when it is pressed uponthe object to be marked.;- and when it is raised from the object to make another mark the spring E will readily pass from oneV notch to the other, the notches being made deeper at their lower ends than above. I

The operation is as follows: When an object is to be marked the stencil-plate is placed over the proper place, and by pressing down the handle thc plate is brought in close contact with the object, when the proper letter or Ligure is made in the usual way. To make the succeeding letter the pressure upon the handle is removed, when the springsforces out the cylinder C, causing the stencil-plate to rise fron-fthe 0bject;`the handle is then turned so as to bring any desired letter or gure in propersucccssion to that already made, so

that by simply turning the handle and plate a series of letters or gures may be made without the necessity of removing the device from the object during the operation oi' marking.

What I claim as my invention, and desire to secure by Letters Patent, is 1. The stencil-plate A, in combination With the shell B, and handle D, substantially as specified, 2. I claim the cylinder C, provided with notches orgrooves, in combination with the spring E, or its equivalent, constructed and operating substantially as and for the purpose specified.

3. I claim the combination of the cylinder C, spring S, and handle D, as set forth. Y In testimony Whereo'f'I have signed my nameto this specification in the presence of two subscribing witnesses.

GEO. R. POWERS.
